The film was outdated. Expiration 10/2011. It was last box of Quickload Acros that I had.
I bought 'enough' quickloads from Tokyo at spring 2009 but as prices went higher and Quickloads disappeared, I kept last box in the freezer (around -28 degree celcius) until november.
I have still around 10 undeveloped sheets. Now I am not sure should I develop them using some other developing style (if the modified Paterson Orbital is cause) or should I investigate this more and use my single sheet stocks for testing.
I guess that Quickloads and normal boxed single sheets has same film base.
